ELASTIC .WHEEL Specification of Letters Patent.

To all 'whom it 'may concern:

Beit known that I, JOHN C. MAoLAcrr- LAN, a citizen of thellnited States, residing 4at Chicago, in the county of Gook and State of Illinois, have invented a certain new and useful Improvement in Elastic Wheels, of which the following is a speciication.

My invention relates to elastic wheels, and is illustrated in the accompanying drawings, wherein- Figure 1 is a vertical section through such wheel; Fig. 2 a side elevation of a portion of the same with parts broken away, and Fig. 3 a detail elevation.

Like parts are indicated by the same letter in all the figures;

.A isthe hub of a wheel having the spokes B Bthereon.

C is a thimble on one end of the hub, and

the spokes are held in position by the cross bolts D D which pass' through a ila-nge E on the hub, a ange F on the thimble and the spokes themselves. Y

J J are annuli secured on the telly K by the cross bolts L'L therethrough, and M is a metallic band encircling the elly. Each of the annuli has at its outer end an eXtens'ion- N, shaped as shown with a collar O overlying the metal piece M, and a series of lugs P whereby it is secured to the opposite extension N by means of a series of links Q Q. Then these parts are assembled as indicated they form a sort of hollow annular chamber about the outer portion of the wheel.

R is a rim U-shaped in cross section, and

containing the tread S and the inwardly projecting flange T which is slotted at U U to let the links QQ, pass, and is provided at its inner end with outwardly projecting plates V V which form seats for the elastic tires W W.

I have endeavored to illustrate an opera` tive and complete form of construction, and yet I wish my drawings to be taken as diagrammatic` because it 1s obvious that many changes may be made without departing from the spirit of my invention, and that the details may be generally altered, some omitted and others substituted.

The, use and operation of my invention are as follows The parts can obviously be Patented Apr. 19, 1910.

Application led August 10, 1908. Serial` No. 447,685.

easily assembled but when they are put together the wheel presents an exterior preferably rubber tread with innerv rotected pneumatic tubes. When the whee sets in the position indicated by Fig. l, the weight of the load is thrown onto the up er portion of the tubes, so that the front oi) the wheel when it descends, compresses these tubes between the extension N and the plates V at the tubes. The tubes are protected and-inan outer tread having an inwardly project-- ing annular flange and supporting plates.

connected thereto within the case, and pneul matic tubes within the case and between the plates and the case wall, said case consisting of two convex rings placed opposite each other and provided with links, and said annular liange perforated to permit the links to pass therethrough.
